Description

Technical Field

[0001] This invention belongs to the field of orthopedic surgery technology, and specifically relates to a grinding device for orthopedic surgery. Background Technology

[0002] In order to improve the cure rate during orthopedic surgery, it is necessary to grind down the injured bone.

[0003] While existing orthopedic surgical grinding devices can meet the basic needs of bone grinding, the distance between the grinding structure and the device body is often fixed and cannot be adjusted. This means that when dealing with patients of different body types, bone thicknesses, or surgical approaches, surgeons cannot flexibly adjust the distance between the grinding head and the device body according to the actual anatomical structure, thus affecting the precision and convenience of the operation. For example, in surgery in space-constrained areas such as the spine or around joints, a fixed distance may prevent the device from entering the target area smoothly, or force the use of a non-ideal angle for grinding, increasing the difficulty and risk of the surgery. In addition, when grinding deep bones, an excessively short distance will limit the depth to which the grinding head can reach, or require time-consuming and laborious disassembly, replacement, and reinstallation of the grinding structure.

[0004] Therefore, there is an urgent need for an orthopedic surgical grinding device that can flexibly adjust the distance between the grinding structure and the device body to meet diverse clinical needs and improve the efficiency and safety of surgery. Summary of the Invention

Detailed Implementation

[0023] To better understand the present invention, the following embodiments further illustrate the content of the invention, but the scope of protection of the present invention is not limited to the following embodiments. Numerous specific details are set forth in the following description to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details.

[0024] like Figure 1 , 6 As shown, a grinding device for orthopedic surgery includes a grinding gun body 101, a cover plate 102 detachably mounted on the grinding gun body 101, a connecting sleeve 103 mounted on the grinding gun body 101, a connecting rod 104 inserted into the connecting sleeve 103, a mounting box 105 mounted on the connecting rod 104, a telescopic push rod 106 disposed inside the grinding gun body 101, the output shaft of the telescopic push rod 106 being connected to the mounting box 105, a grinding motor 107 disposed in the mounting box 105, and a grinding head 108 detachably mounted on the output shaft of the grinding motor 107 and located outside the mounting box 105.

[0025] like Figure 1 , 3 As shown, at least one connecting sleeve 103 is also screwed with a locking bolt 109, and the connecting rod 104 is provided with a plurality of locking holes 110 connected to the locking bolt 109, and the plurality of locking holes 110 are evenly distributed on the connecting rod 104.

[0026] like Figure 1 , 4 As shown in Figure 5, the grinding gun body 101 is slidably connected to the cover plate 102. The grinding gun body 101 is provided with an inlet / outlet hole 201 that is adapted to the cover plate 102. The grinding gun body 101 is also provided with connecting grooves 202 located on both sides of the inlet / outlet hole 201. The cover plate 102 is provided with a connecting slide plate 203 that is slidably connected to the connecting grooves 202. The slot of the connecting groove 202 and the vertical section of the connecting slide plate 203 are both T-shaped. The cover plate 102 is provided with a fastening bolt 204 for screwing the grinding gun body 101. The grinding gun body 101 is provided with a threaded fastening hole for screwing the fastening bolt 204.

[0027] like Figure 1 , 5 As shown, the cover plate 102 is also provided with a sliding groove 205, and the grinding gun body 101 is provided with a first anti-slip texture 206 located in the sliding groove 205.

[0028] like Figure 1 , 5 As shown, the fixed end of the telescopic push rod 106 is connected to the inner wall of the grinding gun body 101. A first through-tube 301, adapted to the output shaft of the telescopic push rod 106, is provided on the side end of the grinding gun body 101. A first sealing ring 302, adapted to the output shaft of the telescopic push rod 106, is provided on the inner wall of the first through-tube 301. The first sealing ring 302, located where the telescopic push rod 106 passes through the first through-tube 301, effectively prevents blood, rinsing fluid, or other contaminants from entering the grinding gun, protecting the telescopic push rod 106 and extending the equipment's lifespan.

[0029] like Figure 1 , 4 As shown, the fixed end of the grinding motor 107 is connected to the inner wall of the mounting box 105, and a second through-tube 303 adapted to the output shaft of the telescopic push rod 106 is provided at the end. A second sealing ring 304 adapted to the output shaft of the telescopic push rod 106 is provided on the inner wall of the second through-tube 303. A first sealing ring 302 is provided at the first through-tube 301 through which the telescopic push rod 106 passes, which effectively prevents blood, rinsing fluid or other contaminants from entering the interior of the grinding gun, protects the telescopic push rod 106 and extends the service life of the equipment.

[0030] like Figure 1 , 3As shown in Figure 4, a mounting sleeve 305 is provided on the output shaft of the grinding motor 107. The grinding head 108 is snapped into the mounting sleeve 305. The mounting sleeve 305 is provided with a mounting bolt 306 for screwing and fixing the grinding head 108. The output shaft of the grinding motor 107 is provided with a threaded mounting hole 307 for screwing and fixing the mounting bolt 306. The grinding head 108 is snapped into the motor output shaft through the mounting sleeve 305 and fixed by the mounting bolt 306. With the help of the guide slider 401 and the slide groove, it can be quickly loaded and unloaded and accurately positioned, which greatly shortens the replacement time and improves the efficiency of surgery.

[0031] like Figure 1 , 4 As shown, the telescopic push rod 106 is an electric push rod. The electric push rod is electrically connected to a control switch 501 located on the outside of the grinding gun body 101 via a wire. The control switch 501 is also connected to a power module 502 inside the grinding gun body 101. The telescopic push rod 106, being an electric push rod, allows for remote control of the extension and retraction of the grinding head 108 via the external control switch 501. Combined with power supply from the power module 502, it enables intelligent control, reducing the doctor's workload and improving the smoothness of the surgery.

[0032] Before the operation, the doctor checked that all components of the grinding device were securely installed and confirmed that the power supply module 502 was functioning properly. The equipment was then started via control switch 501, and the electric push rod and grinding motor 107 were in standby mode.

[0033] Based on the depth and angle requirements of the surgical site, the output shaft of the telescopic push rod 106 is telescopically adjusted. With the insertion guide cooperation of the connecting rod 104 and the connecting sleeve 103, the mounting box 105 and the grinding head 108 are stably translated and adjusted, thereby realizing the adjustment of the distance between the grinding head 108 and the grinding gun body 101. This allows for flexible adjustment of the distance between the mounting box 105 and the grinding head 108 and the grinding gun body 101 to adapt to the needs of different anatomical structures.

[0034] After adjusting the position of the grinding head 108, the locking bolt 109 can pass through the side wall of the connecting sleeve 103 and connect with the locking hole 110 at the corresponding location. This makes the connection between the adjusted connecting rod 104 and the connecting sleeve 103 more stable and prevents the telescopic push rod 106 from being easily damaged due to bearing the reaction force alone. When the position of the grinding head 108 needs to be adjusted again, simply loosen the locking bolt 109 in advance to separate it from the corresponding locking hole 110 and release the fixation of the connection between the connecting sleeve 103 and the connecting rod 104.

[0035] The first sealing ring 302 on the inner wall of the first through-tube 301 can effectively prevent contaminants such as blood and rinsing fluid from entering the interior of the grinding gun body 101, thus protecting the telescopic push rod 106; the second sealing ring 304 on the inner wall of the second through-tube 303 can effectively prevent contaminants such as blood and rinsing fluid from entering the interior of the mounting box 105, thus protecting the grinding motor 107.

[0036] After the grinding motor 107 starts, it drives the grinding head 108 to rotate at high speed. The grinding head 108 is engaged with the motor output shaft by the mounting sleeve 305 and fixed in the threaded mounting hole 307 by the mounting bolt 306, ensuring a stable connection and quick replacement. The guide structure (such as the sliding groove 205 and the first anti-slip texture 206) assists in positioning and improves operational stability.

[0037] When it is necessary to replace the grinding head 108 or to inspect the internal components, loosen the fastening bolts 204 to separate them from the corresponding threaded fastening holes, and release the fixation of the connection between the cover plate 102 and the grinding gun body 101. Under the sliding cooperation of the connecting slide 202 and the connecting slide plate 203, the cover plate 102 can be slid open along the connecting slide 202. The T-shaped connecting slide 202 and the connecting slide plate 203 ensure that the cover plate 102 slides stably and does not shift laterally or vertically. After opening, it can directly contact the grinding motor 107, wiring or telescopic push rod 106, which is convenient for cleaning, maintenance or replacement of parts, and meets the sterility and maintainability requirements of medical equipment.

[0038] After the procedure, the power was turned off, the 108 abrasive head was removed and disinfected. The entire equipment was cleaned and sterilized according to regulations to prepare it for the next use.

[0039] According to another embodiment of the invention, such as Figure 2 , 3 As shown, a guide slider 401 is also provided on the inner side wall of the mounting sleeve 305, and a guide groove 402 that is slidably connected to the guide slider 401 is provided on the outer side wall of the grinding head 108. Through the sliding cooperation between the guide slider 401 and the guide groove 402, the insertion process of the grinding head 108 and the mounting sleeve 305 can be guided, so that after the grinding head 108 and the mounting sleeve 305 are inserted together, the position of the threaded mounting hole 307 can correspond to the position of the mounting bolt 306, thereby making it easier for the user to screw the mounting bolt 306 to the threaded mounting hole 307, and thus making it easier to fix the connection between the mounting sleeve 305 and the grinding head 108.

[0040] According to another embodiment of the invention, such as Figure 1 , 4As shown, the handle portion of the grinding gun body 101 is covered with an anti-slip soft rubber layer 403, and the surface of the anti-slip soft rubber layer 403 is provided with a second anti-slip texture 404. The handle portion is covered with an anti-slip soft rubber layer 403 with a wavy texture, which enhances the friction when the doctor holds it and reduces the risk of slipping during the operation; at the same time, the sliding groove 205 on the cover plate 102 cooperates with the first anti-slip texture 206 to further improve the assembly stability and operating feel.

[0041] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
